Sole F89 FitScore
FitScore rates each treadmill on six categories from structured product data, weighted for one buying intent. The Sole F89 is bought mainly as a premium home treadmill, so this review uses the weights of our best premium treadmill guide, where it ranks #2 with the same score. Performance and durability count most (25% each), then comfort and features (20% each) and practicality (10%), with affordability at 0%, because premium buyers are paying for running quality, longevity and a full feature set rather than the lowest price. For this intent, a membership app with a workout library counts as a feature, since buyers pay for the latest workouts and videos.
FitScore for Premium Home Gyms
How this FitScore was calculated
This FitScore combines 6 category scores using the weights of the buying intent above.
- Performance (100): 4.0 HP motor, 12 mph, 15% incline and 6% decline.
- Durability (93): lifetime frame and motor, 3-year parts and a 375-lb rating.
- Features (96): 21.5-inch touchscreen, Bluetooth and built-in programs, with no required membership.
- Comfort (88): wide 22 × 60-inch cushioned deck with a firm, stable feel.
- Practicality (51): folds, but it is heavy and tall when folded.
Design and Build Quality
The F89 uses a heavy frame with a 22 × 60-inch deck and a release lever for folding. At about 314 lb, it feels planted, and independent testers found it stable enough to sprint on without wobble, describing the frame as close to commercial grade.
That weight means it will not move easily between rooms. Plan where it lives before delivery.
Bottom line: premium build in a folding frame.
Motor and Running Performance
The 4.0 HP motor drives a 0.5–12 mph range, enough for long runs, tempo work and steady intervals. Independent testers found the motor quiet during speed and incline changes.
The trade-off is response time. Testers found it slower to respond to speed changes than some rivals, and one hands-on test timed about 40 seconds to go from 1 to 12 mph, which makes short sprint intervals less practical. The same test measured about 65 dB at 12 mph. Quick keys do not cover every value, so fine adjustments go through a lever near the handrail.
Bottom line: excellent for steady running, less ideal for rapid pace changes.
Running Deck and Cushioning
The 22 × 60-inch deck is spacious, with room for a wide gait. Independent testers called it one of the largest decks they have seen on a folding treadmill. Sole’s Cushion Flex Whisper Deck absorbs more impact than the road, but testers describe it as firm and supportive rather than soft, which may not suit runners with sensitive joints.
One tester found her feet brushing the motor hood while walking on a decline, so stay centered on the belt in downhill sessions.
Bottom line: roomy and stable, with moderate cushioning.
Incline and Programs
Incline reaches 15% and decline goes to 6%, and testers found the motor responsive across the full range. That makes the F89 one of the most versatile folding treadmills for hill training. One hands-on test measured the top incline at about 13.7% and the deepest decline at about 4.7%, and noted that level 0 sits slightly inclined, so a touch of decline is needed to run truly flat.
Built-in programs include Manual, Hill, Fat Burn, Cardio, Strength, HIIT, two user programs and two heart rate programs, so you can train without an app.
Bottom line: one of the widest incline and decline ranges in a folding treadmill.
Console, Apps and Subscription
The 21.5-inch touchscreen is large for a treadmill that needs no membership. Bluetooth connects to speakers, heart rate monitors and fitness apps.
Independent testers found free classes in the SOLE+ app and built-in streaming apps that need no subscription, but the screen is fixed and hard to reach mid-run, volume is adjusted on screen only, the fans are weak and the console takes about 45 seconds to boot. Some owners mention that transferring workouts goes through the SOLE+ app and that not every metric, such as total elevation, syncs.
Bottom line: a big screen and no required subscription.
Footprint, Folding and Noise
Assembled, it needs about 83 × 38 inches of floor space. Folded, the depth drops to about 44 inches, but the deck stands about 71 inches tall, and testers found it takes real effort to tip the 314-lb frame onto its wheels.
Testers and owners describe the motor as quiet. One owner mentions a localized squeak under the deck that a technician resolved with simple lubrication.
Bottom line: it folds, but it still needs a dedicated room.
Delivery, Warranty and Support
The F89 ships by freight with curbside delivery, and assembly services, if selected, are not handled by Sole. Plan for help moving it into place.
The warranty covers the frame and motor for life, with 3 years on parts and 1 year on labor.
Bottom line: strong core coverage for a premium folding treadmill.

Alternatives to the Sole F89
Higher capacity, no fold: Choose the Sole TT8 if you have a permanent spot and want a 400-lb rating with the same motor and incline range.
Faster controls: Choose the Horizon 7.4 AT if you run intervals and want quick speed and incline changes, 15% incline and 5-year parts coverage.
Guided classes: Choose the NordicTrack Commercial 2450 if you want 14 mph, a 24-inch touchscreen and iFIT classes (membership required).
Peloton classes: Choose the Peloton Tread if you want Peloton classes on a 24-inch screen and do not need folding or decline.
Final Verdict
The Sole F89 is the premium folding treadmill we would check first if you want incline, decline and a big touchscreen without paying for a membership. It is heavy and slower to change speed than some rivals. If you run fast intervals, the Horizon 7.4 AT is the better fit; if you have a permanent spot, the Sole TT8 adds a higher weight rating.
